TYPEWRITING MACHINE.

Appli-cation tiled November This invention relates to means for quickly collating Work-sheets in typeWriting machines used in some systems of bookkeeping where each time a bill is typed, it is first collated with a ledger-sheet, and then both sheets Y are fed around the platen to the typing line, the items typed upon the bill-sheet being manifolded in proper line-space order for posting upon the ledger-sheet.

ln the patent to Dennis, No. 1,180,250,dated April 1S, 1916, means are shown Where two sheets may be collated relatively to each other and to the typing line by the use of a table at the introductory side of the platen having line-spac-ereadings along the edge thereof to which numerals previously printed linespace distances apart along the edge of the rear face of the Work-sheetsare aligned to relatively displace t-he sheets, the relative displacement being predetermined by a reading of other numerals printed along the edges of the front faces of thesheets indicating the line-space position of each sheet to be sin'iultaneously typed. These sheets must be aligned with one another, and there must be alignment With the typing line and With a numbered scale line on the edge of the collating table. lt therefore involves effort on the part of the operator to avoid kmistakes and produce neatly and evenly typed records on the covered-up ledger-sheet.

ln the patent to Hilsee, No. 1,426,077, dated August l5, 1922, the numbering at the edges of the work-sheets is Whollyeliminated and for the class of posting described by l-lilsee where single-line entries have a fix-ed daily or monthly line-space position on the ledger or record sheet, the substitution of the sheetend gage for uniformly collating the ledgersheets for a daily or monthly single line entry 4simplifies the Dennis mode of operation, anc greater speed and accuracy are secured, Where a large quantity of single-line daily and monthly records are to be posted. If, however, the character of the posting requires a second collation of the same record-sheet during a daily or monthly interval, it is obvious that the sheet-end gaugeemployed for the first collation of the record-sheet could not be employ-ed for the subsequent collating operation, without a corresponding readiustnient ot said gage, or the readjustment of the platen-stops; or the operator must first collate the sheet by the end gage setting and 18, 1925. Serial No. 69,761,

then manually advance the sheet and platen one 'line-space distance before the statement or bill sheet is collated at the leading-in stops at the rear of the platen. And While the Hilsee device is mechanically effective for a class of ledger posting requiring' single-line entries only at fixed intervals, the employment of the device for a class of mixed postings constantly varying during a fixed interval of time Would require an additional manually-collating operation that would confuse the operator, as it would involve properly collating Work-sheets that require dissimilar collating operations. Furthern'lore, in such a method of collating mixed Work-sheets, some of which would require more lines than others, the blank spaces on the ledger-sheets Would have to be made Wide enough to receive the maximum number of typed lines required on any one of the bill-sheets for a daily or monthly interval, which, of course, Would render the printed forms cumbersome and wasteful of space.

The present invention presents improvements over both Dennis and Hilsee, by eliminating the printing of all numerals along the edges of the rear faces ofboth Work-sheets, and having numerals printed along one edge of the front Vface of the ledger or Work sheet only, numerals that do not co-operate with scale-readings on the collating table in the manner of Dennis or require the daily and monthly adjusted rear-end sheet gage of Hilsee. 'it is the purpose of the present invention to provide the face oi the ledger-sheet with marginal numerals beginning at 1 at the top of the sheet, for theV purpose of numerically indicating line-space positions, down the ledger-sl1eet, to enable the operator to see at a. glance the numbered position of the next line to be typed thereon. A collating table at the rear of the platen is provid-ed With a collating plate or sheet-end scale having serially-numbered lines thereon readable by the eye, or progressively-nuinbered irregularities diseernable by the sense of touch. The ledger-sheet is forced around the rear of the platen and under the cast-ott' feed-rolls. lf a reading of the sheet indicates that the line 6 is the next line thereon to be typed, the rear end of the sheet is aligned to the scalereading on the collating plate marked 6, or a'special index line upon the sheet aligned to a predetermined line on said scale, or the lOO .feeding relation against the platen.

Y sweep of the lever carriee hoth work-sheets to the typing line thereon to rece-ive the singlo-line entry.

'It the ledger-sheet typed upon at line (l, Iniet described, ie subsequently to lloe typed upon line 7, it is reineerted at the rear of the platen as before, to align the bottom edge et' the sheet to the 7 `scale-readingI on the collating plate, and the lsheet ie collated relatively -to the leed-roll poeition without printing numerals along the edge of the rear Yliace ol the sheet ind without the .inentaletlort required in aligning numerals upon the workaheet to dissimilar' numerals at the edge .of the collvating` table of Dennis or any change in the mode et operation, as require-d by Hilsee when two or more linesv are typed within a daily or monthly interval. `The present organization ol the parts provides a novel mode otoperation for collating the two work-sheets that is Aunitorrnly the name regardless of the relative displacement oit the two sheets when collateffl, regardless of the number ot consecutive entries made within a predetermined daily or monthly 'interval of time, and requiring no readjustment ol' the work-sheeteleinent at any time.

handle, said means consisting of a movable plunger l5, which is radially mounted to interlock with Vholes in a-stationary plate 16, pivotedon the platen-aide l'l,'as more clearly shown in the patent to Henning, dated May 5, llllil, No. 1,095,573.

@recording to the method ol.handling,r the work in this invention, a ledger-sheet ll' is inserted at the rear of the platen to reet upon a rear paper-table 1S, and squared against a long sheet-edge guide 19, said'gu'id'e Vbeing,A slidahly mounted on screwsQO, engaging with elongated Slots 2l in eaid guide. The ledger sheet. inserted upside down, in the usual mann and one torni of `the invention may be provided with an indexing line Q2 -at the el; thereof, positioned to align -with any one ot a series ot' lines designated by the numeral 23 marked on a c ollating` plate Ell. Said plate adjuetably secured 'by screwN 25, which page through. slots 2G and thread into the table l, .-:o tr at the lines on the plate will be continuation ot line-space distances trom the typing line. t will be understood that previouslyV to ineerting the ledger-sheet around the platen, the regu-lar (leed-rolle 2T are released means of a handle 28, to permit the tree sliding insertion of the sheet. Said feedrolls are pivotally mounten on a shalt 29, and may be released by means ot' a second shalt 30, operatively connected to the Finger-piece 28 by means oi a link 3l.

After positioningthe let ger-sheet, the feedrollsare rendered operative, andP then a bill- Sheet 232, together with an associated sheet et carbon 33, ie ineerted in hach of the ledgereheet, over the rear table, and is 1forced downwardly against the rear feed-rolls. Since the feed-rolls are in `their operating position, it will be clear that if lthe handle l2 is earring rearwardly, both the Aledger-sheet f d the hill-sheet will be rotated with the platen.

rlhe ledger-sheet torinis provided with a series of lines Sil. printed upon the front face tliereot'line-space distances apart to correspond with the line-spacing of the platen. The linee are consecutively numbered starting' at the top of the sheet with the numeral 1. Previously to inserting,` the sheet around the platen, a reading is taken of the last line oit typing;` on the sheet, so as toV ascertain 'the no niher :tor the next line to be typed thereon. Tl en the sheet 'ie inverted and is reversed, so that the front thereof will face the rear table. and the line Q2 on the haelt ot the sheet indexed toa linnen the collating,l plate ninny in which the platen-axle 11 is j ournaled.

vbered correspondingly to the number of theI lines being spaceddistances corresponding to the line-spacing on the ledger-sheet. At the outer end of each line, preferably at the righthand side of the plate, there are provided identification numbers 36, which are numbered from top to bottom for a length equivalent to the total length oi' the ledger-sheet. In the present form there are provided tittytwo line-spaces.

According` to another form ot the invention, the collating plate 3'4" may be provided with corrugations or groovesBS, the numbers 36 being stamped into the grooves. One advantage of this form of the invention is, that the trailing edge of the ledger-sheet may be readily aligned with the corrugations by the sense ot touch preparatory to squaring the sheet against the gage 19.

In the Underwood machineV there is provided a platen-trame having end plates 89, The rear paper-table 18 is secured to a cross-bar 40,

, which is, in turn, secured, by means of screws 41, to the end plates 39.

According to one form of the invention7 the collating plate 37 is removably secured to the paper-table by a rolled edge 42, designed to snugly lit over the rolled upper edge '43 ot' said table. It will be understood that the plate 24 may be provided with a rolled edge similar to the plate 37, or that the latter may be provided with slots similar to the slots '26 in the plate 24.

Referring more particularly to Figures 1 and 2, in which the work-sheets are shown betere and aiter operation of the sheet-inserter, it will be noted that the sheets are respectively shown in full and dot-and-dash lines, the lattershowing the position of the lsheets for receiving typing theron by means ot' type-bars 44.

1t is the preferred form of: the invention that the line 22 be omitted and that no printing whatever be required upon the back of the ledger-sheet, and that where the form of collating plate shown in Figures 1 and 2 or the corrugated torni of plate shown in Figure 4 is employed, the bottom edge of the ledger-sheet will be aligned to either form to establish the collated position oi' the sheet to the neXt line to be typed. It, in the printing of the ledgersheet, gage-pins are used in the printing press to bear against the bottom edge of the sheet, the spaced-oitI numbered lines on the sheet will be accurately printed relatively to the bottom gaged edge, and the subsequent alignment oi' this bottom edge to the accurately adjusted collating plate will be productive of neat, uniformly line-spaced typing upon the covered-up ledger-sheet, the corrugated form shown in Figure 4 being especially advantageous by enabling the operator to press the rear edge into a groove to register with a rib separating two adjacent grooves which ailiords a speedier alignment ot the work-sheet than Where said edge is brought into alignment with a line on the tace ot the collating plate. It the corrugated collating plate were wider than that shown in the drawings, to correspond practically to the width ot the ledger-sheet, the alignment ot the bottom edge of the sheet to the ribs` formed by the corrugations would also square the ledger-sheet to the typing line and take the place ot the long sheet edge gage 19.

` 1t will be noted that the numeral designations indicating line-spacc distances upon the collating plate are numbered from l at the top down to 52 at the rear of the platen. Reading the number of the next line to be typed upon the tace ot the ledger-sheet and then adjusting the bottom edge to a similar scale-reading on the collating plate is a very simple mode of operation compared to the operation required by Dennis where the sheetedge numerals are continually shitting in relation to the numbers on the lixed collating table, taxing the mind of the operator to properly align tivo rows of mixed figures that in themselves do not suggest the actual linespace positions in consecutive order, as employed in the present invention.

Variations may be resorted to within the scope of the invention, and portions ot the improvements may be used without others.
